Question

Six apples and one pear cost $1.07. At the same price, three apples and six pears cost $1.47. An apple costs

Answer 1

Answer:
`\$0.15`

Explanation:

Given

Six apples and one pear cost
`\$1.07`

Also, three apples and six pears costs
`\$1.47`

Suppose
`x` and
`y` be the price of apple and pear. So, we can write the cost as

`\Rightarrow 6x+y=1.07\quad \ldots(i)\\\Rightarrow 3x+6y=1.47\quad \ldots(ii)\\\text{solve (i) and (ii) we get}`

`x=0.15,\ y=0.17`

The cost of an apple is
`\$0.15`
